This MIB object contains information about traps that an SNMP subsystem that supports the RDBMS MIB can generate. In this case, the SNMP subsystem is OnSNMP.
When a database server changes from its current status to any less-available status, OnSNMP sends a rdbmsStateChange trap message to configured network hosts through the master agent.
The following list summarizes this trap:
For Extended Parallel Server, if the entire database server becomes unavailable, each coserver causes as many traps to be generated as there are available databases.
